梨是我国栽培历史悠久的水果之一,不论山地或平原,在我国各地均有栽培。我场林科所共有梨园160亩,大多是砂梨系统中的日本品种,在我场立地条件下,管理得当,一般表现较好。自1971年以来,产量逐年上升,1980年总产达36万斤,折合亩产2,250斤。单株最高产量为420斤。我们在梨园的栽培管理中有如下体会: 一、轻修缓放可促使幼树早成形早结果日本梨品种在洞庭湖区自然条件下大多表现有生长快结实早的特点,一般定植二、三年即能开花结果。一经开花结果,就要力求平衡树势,使生殖生长和营养生长平衡协调,达到既长树又结果的目的。但在生产实践中,往往从定植开始就着重树体整形,采取较重的修剪,导致结果年龄和树冠扩大都明显推迟,出现越剪越旺长,越剪越不结果。我场1969年建的梨园,开头6—7年内采取轻剪轻截 Pear is one of the cultivated fruits of our country, cultivated in all parts of China, regardless of the mountain or plain. My field Linke total of 160 acres of pear orchard, mostly sand pear system in the Japanese species, site conditions in my field, properly managed, the general performance is better. Since 1971, the output has been increasing year by year, with a total output of 360,000 kg in 1980, equivalent to 2,250 kg of mu per mu. The highest yield of 420 kg per plant. We pear cultivation and management of the following experience: First, the light repair can promote the early formation of sapling Early results Japanese pear varieties in the natural conditions in the Dongting Lake area most of the performance of fast growth and early fruiting characteristics, the general planting two or three years That is able to bear fruit. Once flowering results, we must strive to balance the tree vigor, so that reproductive growth and nutritional balance of growth and balance, both to achieve the purpose of both trees and results. However, in the practice of production, it is often emphasized from the beginning of colonization that the plastic body of the tree should be sharpened and heavier pruning should be carried out. As a result, the age and the crown of the tree are obviously delayed. My field pear garden built in 1969, the first 6-7 years to take light cut light cut
